Operating system name and version: HP ProLiant / Debain Lenny
Version of smsd: 3.1
Smsd installed from: debian repository
Name and model of a modem / phone: Siemens TC35
Interface: serial

Hello,

I have a problem accessing the TC35 via serial port on Debian Lenny. However, I am able to access the modem on Windows via Hyperterminal and send SMS sucessfully with the same serial cable. Hence, the problem has to be Linux configuration related.
I suspect that the serial port configuration is broken and I have to admit that I am a Linux novice and just followed several tips on the internet to solve the problem. I am aware that my question is a bit off topic, but after trying for a long time I would appreciate any help.

I tried the tips here to check if the modem is connected http://axion.physics.ubc.ca/modem-chk.html but no modems got recognized.

Also, I tried to access the modem via minicom but there is no reaction from the modem (I type some characters in but they do not appear in minicom though minicom says "connected").

The /dev/ttyS0|1 is readable and writeable.

setserial -g /dev/ttyS* /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3

I have to say that I do not know how to resolve this problem.

As you have tried both ports with smsd and with minicom, the baudrate could be changed if it was different when testing with Hyperterminal.

I'm running Ubuntu on HP ProLiant ML110 and there was no problem with a serial modem:

# cat /etc/debian_version lenny/sid

# ls -l /dev/ttyS* crw-rw---- 1 root dialout 4, 64 2010-04-22 15:06 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 2008-08-28 14:55 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 2008-08-28 14:55 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 2008-08-28 14:55 /dev/ttyS3

# setserial -g /dev/ttyS* /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

Perhaps you could try to type ATE1 (and Enter), if there is "echo off" in the modem. But if you type just something (and Enter), the modem should answer ERROR. Or if you type AT, the answer should be OK. However, I do not think that this helps...

SOLVED.

I did a complete reset of the BIOS as well as the iLo2 configuration to factory settings.
